[android] 메뉴 항목 클릭 이벤트 처리-Android

메뉴 항목을 클릭하면 새 활동을 시작하는 인 텐트를 만들고 싶지만이 작업을 수행하는 방법을 모르겠습니다. 나는 안드로이드 문서를 읽었지만 내 구현이 정확하지 않으며 올바른 방향에 대한 지침이 도움이 될 것입니다. 아래에 내 코드를 나열하고 문제 영역에 주석을 달았습니다. 잘못된 메서드를 호출 한 것 같습니다.

  Button GreenButton;   // Declare instances of buttons to use later
  Button BlueButton;

  private static final int OK_MENU_ITEM = Menu.FIRST;

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    BlueButton = (Button) findViewById(R.id.bluebutton);
    BlueButton.setOnClickListener(new View.OnClickListener() {

      public void onClick(View v) {

        //Display msg when user clicks Blue Button
        showColorChangeMsg();

        // Switch Activities on click
